Abstract

Selon des modes de réalisation, la présente invention concerne un nœud B évolué (eNB) pour la prise en charge de services à commutation de paquets (PS) en fonction de supports EPS. L'eNB peut recevoir un message de configuration de support EPS provenant d'une MME, afin de configurer un support EPS pour un service PS entre un équipement utilisateur (UE) et une PGW. Ledit message de configuration de support EPS peut comprendre un indicateur de surveillance pour le service PS, qui indique si le trafic du service PS est surveillé ou non au niveau de l'UE. En outre, l'eNB peut transmettre des paquets de trafic à l'UE et recevoir des paquets de trafic en provenance de l'UE (102) au cours du service PS. De plus, l'eNB peut utiliser l'indicateur de surveillance lors de la régulation de l'encombrement au sein du réseau.
